Sachin Singh, Zach to his friends, looks like a regular seventeen-year-old. The truth is a lot older than that.

Beneath the Atlantic, there is a city older than any civilization on the surface. The beings who built it were known as gods to the ancient world. For thousands of years they have protected a world that has no idea they exist.

Atlantis is not a legend. It is a story the world forgot was real. And three days ago, the people who live there came to Miami to find Zach.

To everyone else, he's still just a teenager. What's underneath is older, stranger, and entirely his problem now.
